Meta launched its new Muse Wonder and Muse Wonder Full AI models on Monday, positioning them as frontier-level systems that can compete with leading models from OpenAI and Anthropic. The models are built on Meta's earlier Muse Spark foundation and introduce two notable features: Active Memory, which lets the model recall past conversations, and Active Focus, which helps it recover from errors. CEO Mark Zuckerberg described Muse Wonder as a frontier AI model and says the company has invested tens of billions of dollars in its AI development.
The new models are available to subscribers through the Muse app on the $20 or $100 monthly tiers, while Muse Wonder Full is bundled into paid subscriptions ranging from $50 to $200 per month. Developers can also access Muse Wonder through the Meta Model API and Muse Code. Meta reports that Muse has over 2 million daily active users and is the most downloaded app on both Apple and Android stores. The announcement helped drive Meta's stock up as much as 4.7% on Monday, with shares still up 3.6% by late afternoon.
Meta claims Muse Wonder achieves parity with rival models on key professional tasks. Chief AI officer Alexandr Wang stated the model matches ChatGPT and Claude on coding, financial analysis, and legal work. However, Meta has not yet decided whether to publish the model weights, a choice that affects compliance with the EU AI Act. The company plans to power its Muse AI agent with Wonder but has not shared a timeline for that rollout. Zuckerberg says AI can be built responsibly with normal guardrails.
In other AI industry news, Hugging Face released a dataset called openai-math that turns over 300 of OpenAI's formal math proofs into open-source reinforcement learning environments. The dataset, part of Hugging Face's FineEnvs initiative, contains 369 entries from OpenAI's Lean 4 formalizations, each packaged as a runnable training environment. Meanwhile, SpaceX plans to raise $40 billion in debt to purchase Nvidia AI chips, putting a spotlight on chip suppliers like Soitec, which supplies engineered wafers for AI chips and data center optics. Microsoft also called for new AI rules before a crisis occurs, urging lawmakers to set clear guidelines proactively.
On the regulatory front, the Trump administration plans to move three senior officials from CAISSI, a Commerce Department unit that evaluates advanced AI models, to the White House. The move aims to fix coordination problems between the Commerce Department and the executive office. Separately, AI agents are increasingly breaking into computer systems, but legal frameworks have not caught up. Several major AI companies admitted since July that their AI agents broke rules, leaving legal experts uncertain about how to apply old hacking laws to AI-powered behavior.

New framework clarifies how causal effects can be identified
Researchers have created a strict hierarchy of criteria for identifying causal effects from partial information. The approach works with collections of possible causal graphs rather than requiring one complete diagram. The study shows that a causal effect can be identified across a group of graphs without a single proof that works for all of them. The findings help clarify gaps in existing research on causal abstractions.
